REAL32 IEEE-754 single precision format, 4-byte
REAL64 IEEE-754 double precision format, 8-byte
Data Swap Displays the following softkeys for enabling or disabling the
byte swap for the IEEE-754 precision format data output. The
present setting is indicated by an asterisk on the softkey label.
OFF Disables the byte swap. Normal byte order.
ON Enables the byte swap. Reverse byte order.
If Data Swap=ON, the byte order is reversed. Byte 1 to byte 4 are sent in the order of
byte 4 to byte 1 for the IEEE-754 single precision format, and byte 1 to byte 8 are
sent in the order of byte 8 to byte 1 for the IEEE-754 double precision format.
